By the way, I get the following error:
Unable to create directory […]/wp-content/uploads/2007/05. Is its parent directory writable by the server?
I’ve already performed a search on this error message, and I’ve tried anything that seemed as though it might work, including deleting and re-creating the uploads folder, as well as messing with the permissions on wp-content.
For the record, the uploads directory is /wp-content/uploads at the moment.
